Used 3d printer, a little dusty. The extruder has been upgraded to fully metallic piece to avoid it getting stuck, and filament is extruded smoothly. The printer has not been used frequently, however the mechanical parts all work very well, no filament stuck in the nozzle head. I have been having problems getting my print to stick to the bed which if i had more patience and time could solve, but as I don't I have decided to sell the device. Regardless, it works fine.
